Mysterium

Mysterium is a first-person dungeon crawl RPG for Game Boy where players control an alchemist's apprentice. The player starts by learning alchemy at Hermetrix and must transmute metals and minerals using pools of fire, water, acid, and mercury to create keys and progress through the Mysterium maze. The main goal is to explore twisting halls created by giant ants, defeat a dragon, and rescue a fellow alchemist. The game mixes alchemy puzzles with exploration and combat in a challenging first-person perspective. It stands out as one of the few first-person dungeon crawlers on Game Boy, with depth in item crafting and progression despite its awkward controls and ugly visuals. No specific character names beyond the protagonist and Hermetrix are mentioned.
